For this condensing tech leader, water is a very hot topic.

Navien is a developer of condensing technology and worldwide producer of items for the plumbing and HVAC sectors. Its flagship residential products are condensing tankless water heaters, boilers and combi-boilers. Navien North America headquarters is in Irvine, Calif. The company’s parent, KD Navien, is headquartered in Seoul, Korea, along with its manufacturing plant, which is the world’s largest single-boiler facility.

EcoLeaders Navien

Navien’s goal is to efficiently develop energy-saving products for the HVAC and plumbing sectors.

The Culver Cove Resort and Conference Center is an 80-unit hotel-condominium complex located near Culver, Ind. Originally, hot water was supplied from three utility rooms, each with six 100-gallon tank-type heaters. Circulating pumps and mixing valves were required to prevent scalding. Rich West, executive director of Culver Cove, was looking for a more efficient hot water system to reduce energy costs, especially during low demand periods.

West worked with Mike Lambert of Mid-City Supply in Elkhart, Ind., and Clark Boyles of P-M & Associates in Indianapolis. They recommended installation of five cascaded Navien NPE-240 units for about one-third of the complex—about 24 to 26 units of one to three bedrooms each. Lambert and Boyles worked with Jason Richards, owner of A+ Plumbing, Heating, Cooling Inc. in Bremen, Ind., to work out details for sizing, designing and installing the system.

Another huge factor in selecting Navien NPE was the internal recirculating pump and buffer tank, which assure an uninterrupted flow of hot water. “We have noticed a decrease in our energy cost from NIPSCO, our local gas supplier—a real dollar savings every month,” West remarks. “I also have seen a decrease in our domestic water use.”
